stat /bin/grpc_health_probe: no such file or directory": unknown

When installing sitewhere，there have some problematical pods .They are "sitewhere-instance-management-6dcc4c447b-k776l " and "sitewhere-label-generation-5fd69fc48b-86cnk".When we describes them,they have the same question :

Successfully pulled image "docker.io/sitewhere/service-instance-management:latest"
Liveness probe failed: OCI runtime exec failed: exec failed: container_linux.go:348: starting container process caused "exec: "/bin/grpc_health_probe": stat /bin/grpc_health_probe: no such file or directory": unknown

The steps when I try to install sitewhere:
helm repo add sitewhere https://sitewhere.io/helm-charts
helm repo update
helm install sitewhere sitewhere/sitewhere

kubectl version is 1.15.1
helm version is v3.0.0
istio version is 1.3.2
docker version is 18.06
sitewhere chart version is 0.2.9
sitewhere app version is 2.1.1

Could you tell me what can I do to fix this? Thank you very much
